新棚建造时,为方便操作,多是将地表层的熟土用挖掘机挖起后,用于堆砌棚墙。而用来种植蔬菜的土壤多是距离地表1.5米左右的生土,这样的土壤有机质缺乏,因此要大量补充有机肥。一是增加鸡粪等粪肥的施用量。新建棚室多是生土,有机质缺乏,因此要大量补充有机肥,像稻壳粪、鸡粪等有机肥,可以将667平方米用量提高到35方左右。这些有机肥施用后,虽不能迅速增加土壤中的有机质,但却可以在一定程度上改善土壤的理化性状。
New shed construction, for the convenience of operation, mostly on the surface of the mature digging excavator, used for piling wall. The soil used to grow vegetables is mostly about 1.5 meters away from the surface of the earth, so the lack of organic matter in the soil, so a large number of organic fertilizer. First, increase manure and other manure application. New greenhouses are mostly raw soil, lack of organic matter, so a large number of additional organic fertilizer, such as rice husks, chicken manure and other organic fertilizer, can increase the amount of 667 square meters to 35 or so. Although these organic fertilizers can not rapidly increase the organic matter in the soil, they can improve the physical and chemical properties of the soil to a certain extent.
